Built to Perform
You count on your truck to tow all of your gear to where you want it. With your MBRP performance exhaust you can make that happen with up to18 HP more horsepower and 28 ft/lb more torque. Give your truck more pulling power and much improved throttle response with an MBRP diesel exhaust system. Our systems are so much more efficient, it will be easy to see what your truck can really do.
Minimize Backpressure
The secret to getting more out of your diesel engine is to give it lots of cool, clean air. The only way that you can get fresh air in is to get the hot air out. From the spiral louvered high flow muffler to the fully mandrel bent tubing to minimal bend degree angles, your MBRP performance system gets exhaust out fast. Drop exhaust gas temperature by up to 200ºF and set the stage for all the performance you want. An MBRP performance exhaust system is the starting point to getting the most from cold air intakes, programmers, modules and downloaders.

Bought the XP kit for my Duramax. Was looking for a richer exhaust note over stock as well as increased power and reduced EGT's. Installation took a couple hours with all the right tools. If you don't have a lift you'lol need to make a cut in the factory exhaust just behind the muffler. A sawzall works good for this. The pictures could have been a little larger and more clear, but the step by step written instructions worked well. The new exhaust looks bad ass and sounds killer. Thanks MBRP and XDP Diesel!
